I'm really glad to read that, Phil. The idea is that it will hopefully give DH something to experiment with now that he's retired. I have so much on my plate at the moment, work wise, that I just don't have the time to spend with him. At the moment, he seems quite enthusiastic - well, he is while I'm around - but only time will tell. The machine does make super bread and is capable of a lot more so here's hoping!
I'm on my second attempt at making a decent hotdog bun as I type. if it comes out as bad as the last batch I'll be looking for the bread machine....and a new recipe.
If you mean the really soft crust fluffy ones, then think fat/oil in the mix, milk instead of some/all the water and adding egg white. Potato or Instant potato powder is also said to help. I also notice white vinegar in some commercial products - I think a small amount helps gluten development. Knead well and leave to rise until well risen - almost the finished size. Keep the hydration fairly high and cook at quite a low temp for as shorter time as possible. The water roux method detailed above will also help.
The bread sure looks the business and contains vinegar. I'd up the hydration from the 56.8% in the recipe to around 65% and try it with half water and half milk...
....or even my rolls recipe with a bit less oil and 10 - 15ml white vinegar added.
